[0002] Offshore hydraulic power generation refers to a method of generating electricity by using natural forces such as water currents and waves in the ocean to convert mechanical energy into electrical energy through a hydraulic conversion device. Usually, the fixed foundation is changed to a floating foundation that floats on the water.

[0003] At present, the existing maintenance mechanism for floating offshore power generation using wave energy has the following shortcomings in use: usually after being put into use, professional personnel are required to go to the sea regularly to inspect and maintain the offshore power generation equipment put into use in different locations. This process takes a long time to complete, with a large workload and a complicated process. When encountering bad weather at the final stage of maintenance, there will be a risk of damage to the offshore power generation equipment that has not been maintained for a long time or even fails. First, in bad weather at sea, excessive waves and fast currents will cause the operating speed of the wave plate and the turbine to increase significantly. Overload work will cause excessive energy dissipation in the internal parts of the hydraulic coupling, reduce transmission efficiency, and even cause component damage. The self-deceleration system may not be able to withstand continuous high-speed operation, and may stall, and may also cause dry wear of internal gear components.

[0020] 1. This scheme transmits mechanical energy through a hydraulic wave energy converter and drives the hydraulic motor to rotate, so that the low-speed shaft is driven to rotate, so that the first bevel gear follows the rotation and drives the second bevel gear to rotate, so that the coaxial second main gear rotates and drives the second sub-gear to rotate, thereby driving the short shaft to rotate and the constant speed cap to follow the rotation, so that the self-adjusting control component works as a whole, and when the hydraulic rod moves, it will penetrate into the oil filling tank, and regularly push the lubricating oil into the transfer oil pipe, and then transport it to the oil box through the main oil vertical pipe, soaking the lower part of the first sub-gear, and the oil stored in the spare oil tank is replenished as the oil amount of the oil ring plate decreases. The first main gear is driven to rotate by the rotation of the low-speed shaft, thereby driving the meshing first sub-gear to rotate. When the first sub-gear rotates, it can carry the lubricating oil soaked in the oil box, and lubricate it as it reciprocates with the first main gear. Therefore, the driven high-speed shaft transmits the mechanical kinetic energy to the generator, and transmits it out through the high-speed shaft. When it is used in a maintenance mechanism for floating offshore power generation that utilizes wave energy, it can automatically add lubricating oil to the internal transmission parts during the operation of hydraulic power generation, prevent the increase of transmission friction under high-speed operation, reduce component wear, and avoid increasing the difficulty and time of maintenance.

[0021] 2.

As the reduction ring rotates and slides, it will drive multiple pressure rods to move, thereby pushing multiple brake pads to frictionally reduce the speed of the brake disc under the top force of multiple pressure rods, thereby reducing the speed of the driven high-speed shaft being pulled by the low-speed shaft. According to the size of the wave energy, it can assist in real-time speed control of the offshore power generation equipment, thereby improving the overall maintenance efficiency and use quality of the maintenance mechanism for floating offshore power generation that utilizes wave energy.

DETAILED DESCRIPTION

[0032] Example 1: Figure 1 - Fig. 9As shown, a floating offshore power generation maintenance mechanism utilizing wave energy solves the problem that in the use of the existing floating offshore power generation maintenance mechanism utilizing wave energy, usually after being put into use, professionals are required to go to the sea regularly to inspect and maintain the offshore power generation equipment put into use at different locations. This process takes a long time to complete, with a large workload and a complicated process. When encountering bad weather at the end of the inspection and maintenance, there is a risk of damage to the offshore power generation equipment that has not been maintained for a long time or even fails. First, in bad weather at sea, excessive waves and fast currents will cause the operating speed of the wave plate and the turbine to increase significantly. Overload work will cause excessive energy dissipation in the internal parts of the hydraulic coupling, reduce transmission efficiency, and even cause component damage. The self-deceleration system may not be able to withstand continuous high-speed operation, and may stall, and may also cause dry wear of the internal gear components. Continuous high-speed transportation without speed reduction will lead to greater dangers, increase maintenance costs, and reduce the overall use and maintenance efficiency and quality of offshore power generation equipment.

[0033] 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.

[0034] Specifically include:

[0035] The offshore power generation reinforced hood 1 is provided with a transfer hood 2 on one side to protect the internal components from being corroded by seawater and avoid the direct effects of wave loads. A balance support bridge 3 is provided on one side of the transfer hood 2. The left and right sides of the balance support bridge 3 are used to connect the second wave plate 12 to capture wave energy for power generation while keeping the two sides of the wave energy power generation device balanced. The lower side of the balance support bridge 3 is used to connect the tidal power generation components to capture tidal energy. The first wave plate 11 is hinged on both sides of the offshore power generation reinforced hood 1. The first wave plate 11 is used to capture wave energy and swings around the hinge point under the action of waves, thereby driving the hydraulic wave energy converter 20 to convert wave energy into hydraulic energy.

[0036] The second wave plates 12 are hinged on both sides of the balance support bridge 3. A hydraulic motor 41 is arranged inside the balance support bridge 3 to convert hydraulic energy into kinetic energy of the hydraulic motor rotation in order to rotate under the impact of high-pressure hydraulic oil.

[0037] A shaft sleeve 7 is installed on one side of the transfer cover 2 for supporting and limiting the bearing of the hydraulic motor. A hydraulic wave energy converter 20 connected to the hydraulic motor 41 is installed in the middle of the balance support bridge 3. The hydraulic wave energy converter 20 converts the kinetic energy of the swing of the first wave plate and the second wave plate into the hydraulic energy of the hydraulic system through the hydraulic system. A tidal power generation component 555 is installed at the bottom end (also the lower side) of the hydraulic wave energy converter 20, and a self-adjusting control component 551 is arranged inside the offshore power generation reinforcement cover 1. The self-adjusting control component 551 adjusts the distance between the top block 29 and the constant speed hood 26 by inertia, thereby adjusting the amount of oil pushed by the oil push plug 44 and controlling the position of the guide rod to regulate the linkage speed control component 552.

[0038] The self-adjusting control assembly 551 includes an oil ring disc 14 fixedly connected to the inner wall of the offshore power generation reinforced hood 1. The oil ring disc 14 is used to connect to the spare oil tank and store a certain amount of lubricating oil, so as to cooperate with the oil push plug 44 to push the lubricating oil into the adapter oil pipe. The upper surface of the oil ring disc 14 is fixedly connected to the spare oil tank 15. The upper surface of the spare oil tank 15 is fixedly connected to the oil filling pipe 4, which is used to manually replenish the lubricating oil in the spare oil tank during a long interval. The spare oil tank 15 is fixedly connected to the inner wall of the offshore power generation reinforced hood 1. The oil filling pipe 4 extends to the outside through the offshore power generation reinforced hood 1 as a subsequent oil replenishment channel for maintenance personnel. A short shaft 47 is inserted and installed in the middle of the oil ring disc 14, which is used to transmit the mechanical rotation of the low-speed shaft 13 to the constant speed cap 26. The short shaft 47 is fixedly sleeved with a constant speed cap 26 at one end close to the oil ring disc 14, which is used to connect the elastic column 27 and the short shaft 47, so that the top block 29 performs a circular motion. An elastic column 27 is fixedly connected to the outer surface of the constant speed cover 26 for connecting the top block 29. One end of the elastic column 27 is fixedly connected to the top block 29. A plurality of arc plates 33 are arranged in an annular shape on the inner side of the oil ring disc 14, so that the arc plates 33 are spliced ​​on the inner side of the oil ring disc to form a circular structure. A hydraulic rod 48 is hinged on the side surface (outer surface) of the plurality of arc plates 33 that are far away from each other, that is, a circle of hydraulic rods 48 is arranged in an annular direction in the space between the arc plates 33 and the oil ring disc 14. An oil filling bin 49 is provided on the outer side of the oil ring disc 14. There are two ways to set the hydraulic rod 48. One is that the hydraulic rod 48 is fixedly connected to the inner wall of the oil ring disc 14. The other is that the hydraulic rod 48 close to the top block 29 passes through the oil ring disc 14 and enters the interior of the oil filling bin 49. The number of hydraulic rods 48 in the second setting method depends on the specific situation. On the one hand, the oil intake of the overall device should be considered, and the total number of hydraulic rods 48 should also be considered. Generally speaking, if Fig. 9 As shown, the three hydraulic rods 48 close to the top block 29 are arranged in the second mode.

[0039] The end of the hydraulic rod 48 that passes through is fixedly connected with the oil push plug 44, that is, the end of the hydraulic rod 48 of the second setting method is fixedly connected with the oil push plug 44, the outer surface of the hydraulic rod 48 is covered with a spring 28, and the outer wall of the oil ring disk 14 is penetrated with an adapter oil pipe 43 corresponding to the oil push plug 44, the number and position of the adapter oil pipe 43 and the oil push plug 44 are matched, and the adapter oil pipe 43 will merge with the main oil vertical pipe 42 in the oil supply path.

[0040] By setting the self-adjusting control component, the moving distance of the arc plate is increased according to the size of the wave energy, which will drive the guide rod to move. When the guide rod is pushed outward, it will drive the multi-directional connecting rod to rotate along the positioning shaft, so that the guide tooth plate is driven to move in the direction of the gate disc, and mesh with the teeth on the reduction ring to drive it to rotate inside the gate disc. As the reduction ring rotates and slides, it will drive multiple pressure rods to move, thereby pushing multiple brake pads to frictionally reduce the speed of the brake disc under the top force of multiple pressure rods, thereby reducing the speed of the driven high-speed shaft being pulled by the low-speed rotating shaft. According to the size of the wave energy, it can assist in real-time speed control of the offshore power generation equipment, thereby improving the overall maintenance efficiency and use quality of the maintenance mechanism for floating offshore power generation that utilizes wave energy.

[0041] A linkage speed control assembly 552 is installed inside the offshore power generation reinforced engine cover 1, and a low-speed rotating shaft 13 is penetrated and rotatably installed inside the shaft sleeve 7. The outer surface of the low-speed rotating shaft 13 that enters one end of the offshore power generation reinforced engine cover 1 is fixedly sleeved with a first main gear 17, and the hydraulic motor 41 between the shaft sleeve 7 and the first main gear 17 is also sleeved on the low-speed rotating shaft 13, so that the low-speed rotating shaft 13 rotates together with the first main gear 17 and the hydraulic motor 41.

[0042] An electricity storage conversion component 553 is arranged inside the offshore power generation reinforced hood 1, a traction shaft push component 554 is arranged on the inner side of the offshore power generation reinforced hood 1, a tidal power generation component 555 is arranged at one end of the offshore power generation reinforced hood 1, a mounting block 30 is fixedly connected to the inner wall of the offshore power generation reinforced hood 1, an oil box 21 is fixedly connected to the bottom end of the mounting block 30, a main oil vertical pipe 42 is vertically arranged inside the mounting block 30, a driven high-speed shaft 31 is clamped on the oil box 21, and the driven high-speed shaft 31 is rotatably arranged in a matching groove of the oil box 21, a first sub-gear 22 is fixedly sleeved on the outer surface of the driven high-speed shaft 31, and the first sub-gear 22 is matched with the oil box 21, so that the oil box 21 covers the first sub-gear 22, the first sub-gear 22 rotates in the space formed by the oil box 21, the first sub-gear 22 is meshed with the first main gear 17, and a heater 25 is arranged on one side of the mounting block 30.

[0043] The tidal power generation assembly 555 includes a drainage tube 18 installed at the lower part of the hydraulic wave energy converter 20, and a transmission 10 is installed inside the drainage tube 18. A guide rod 9 is arranged on one side of the transmission 10, and a frame 8 is arranged on the surface of the end of the guide rod 9 away from the transmission 10. The circumferential extension of the frame 8 is in contact with the drainage tube 18 to support the internal space of the drainage tube 18, and then a turbine 6 is installed at the end of the frame 8 away from the transmission 10. The turbine 6 is connected to the guide rod 9. The turbine 6 can rotate around the guide rod 9, and the circumferential extension of the turbine 6 will not contact the drainage tube 18, so that it can rotate freely around the guide rod 9 in the internal space of the drainage tube 18, thereby maximizing the use of the mechanical power caused by the water flow passing through the drainage tube 18.

[0044] According to the above technical solution, the turbine 6 is rotated according to the impact force of the ocean current, and then the mechanical energy is converted into electrical energy through the transmission 10 to increase the power generation. At the same time, the undulating motion of the waves is used to drive the first wave plate 11 and the second wave plate 12 to reciprocate. The mechanical energy is transmitted through the hydraulic wave energy converter 20 and the hydraulic motor 41 is driven to rotate, so as to drive the low-speed shaft 13 to rotate. Since the outer surface of the low-speed shaft 13 is fixedly sleeved with the first bevel gear 34, the first bevel gear 34 rotates with it, and then drives the meshing second bevel gear 35 to rotate. After the second bevel gear 35 rotates, it drives the coaxial second main gear 23 to rotate, and further drives the meshing second auxiliary gear 23. The gear 36 rotates, and because the lower part of the short shaft 47 is fixed with a second sub-gear 36, the short shaft 47 is driven to rotate and the speed cap 26 rotates accordingly, so that the elastic column 27 makes a circular motion around the short shaft 47. When the elastic column 27 contacts the top block 29, due to the obstruction of the top block 29 and the continuous circular motion of the short shaft 47, the elastic column 27 gives the top block 29 an outward thrust to make it move. At the same time, the surface of the contact part of the top block 29 and the arc plate 33 is set to be an arc shape, which can reduce the friction between the top block 29 and the arc plate 33, so that when the top block 29 makes a circular motion along the arc plate 33, the impact force when the top block 29 transitions to other arc plates 33 is reduced. The top block 29 is an inertial structure with a large mass. When the rotation speed of the short shaft 47 is low, the top block 29 does not contact the arc plate 33, and there is no need to lubricate the system. When the rotation speed of the short shaft 47 is relatively high, the push block 29 is subjected to a greater centrifugal force, so that it moves outward along the axial direction of the elastic column 27 under the action of the elastic column 27 , thereby pushing the arc plate 33 .That is, when the top block 29 moves, it will move circumferentially on the inner side of the oil ring disk 14, and then reciprocately contact with the arc plate 33. When contacting a certain arc plate 33, it will drive the corresponding hydraulic rod 48 to elastically expand and contract, and contact with the spring 28. When the hydraulic rod 48 arranged in the second way is acted on, the hydraulic rod 48 will be inserted into the oil filling tank 49. Because the top is provided with an oil push plug 44, the lubricating oil stored in the oil filling tank 49 is regularly pushed into the transfer oil pipe 43, and further flows into the main oil vertical pipe 42, and then flows from the main oil vertical pipe 42 to the oil box 21, soaking the lower part of the first sub-gear 22. During maintenance, personnel can regularly inject lubricating oil from the oil filling pipe 4 and then enter the spare oil tank 15. The oil ring 14 is reserved, and as the amount of oil inside the oil ring 14 decreases, subsequent replenishment is carried out. The first main gear 17 is driven to rotate by the rotation of the low-speed shaft 13, thereby driving the meshing first sub-gear 22 to rotate. When the first sub-gear 22 rotates, it can carry the lubricating oil soaked in the oil box 21, and lubricate it as it reciprocates with the first main gear 17, so that the driven high-speed shaft 31 transmits the mechanical kinetic energy to the generator 19, and transmits it out through the high-speed shaft 24. When it is used in a maintenance mechanism for floating offshore power generation that is beneficial to utilizing wave energy, it can automatically add lubricating oil to the internal transmission components during the operation of hydraulic power generation, prevent the increase of transmission friction under high-speed operation, reduce component wear, and avoid increasing the difficulty and time of maintenance.

[0045] A further technical solution is that the linkage speed control component 552 includes a gate disc 16 fixedly connected to the inside of the offshore power generation reinforcement cover 1, a reduction ring 37 is slidably provided on the inner side of the gate disc 16, and a plurality of pressure rods 46 are rotatably connected to the inner side of the reduction ring 37, and a plurality of gate pads 45 are rotatably connected to the inner side of the gate disc 16, and the plurality of gate pads 45 are rotatably connected to the pressure rod 46, and the plurality of gate pads 45 are used in conjunction with the brake disc 32, and a first bevel gear 34 is fixedly mounted on the outer surface of the low-speed rotating shaft 13, and a second bevel gear 35 meshing with the first bevel gear 34 is rotatably connected to one side of the gate disc 16, and a second main gear 23 is rotatably connected to the second bevel gear 35, and a second sub-gear 36 is fixedly mounted on the lower part of the short shaft 47, and the second sub-gear 36 meshes with the second main gear 23.

[0046] The power storage conversion assembly 553 includes a generator 19 disposed inside the offshore power generation reinforcement hood 1 , one end of the generator 19 is connected to a high-speed rotating shaft 24 , and the generator 19 is connected to a driven high-speed shaft 31 .

[0047] The traction shaft push assembly 554 includes a positioning shaft rod 40 rotatably connected to a side wall of the oil box 21, and a guide rod 50 is movably sleeved on one side of the positioning shaft rod 40. The guide rod 50 is interspersed with the oil ring disk 14 and enters the oil filling tank 49 to be hinged to a corresponding arc plate 33. The bottom end of the guide rod 50 is fixedly connected to a multi-directional connecting rod 39, and the bottom end of the multi-directional connecting rod 39 is rotatably connected to a guide tooth plate 38. The lower surface of the reduction ring 37 is provided with a plurality of teeth, which are meshed with the guide tooth plate 38 for use.

[0048] According to the above technical solution, the speed-regulating cap 26 can be set to determine the rotation speed according to the size of the wave energy. When the wave energy is too large, the speed-regulating cap 26 rotates fast, so that the top block 29 has a large rotational inertia, thereby stretching the length of the elastic column 27, so that the top block 29 pushes the arc plate 33 with greater force, further increasing the moving distance of the arc plate 33. When it moves to the corresponding arc plate 33, it will drive the guide rod 50 to move at the bottom end of the oil ring plate 14. There is a sealing gasket at the position where the guide rod 50 and the oil ring plate 14 are interlaced to prevent the lubricating oil from leaking. When the guide rod 50 is pushed outward, it will drive the multi-directional connecting rod 39 to rotate along the positioning shaft rod 40. The guide tooth plate 38 is driven to move in the direction of the gate disc 16, meshed with the teeth on the reduction ring 37 and driven to rotate inside the gate disc 16. As the reduction ring 37 rotates and slides, it drives multiple pressure rods 46 to move, thereby pushing multiple brake pads 45 to frictionally reduce the speed of the brake disc 32 under the top force of the multiple pressure rods 46, thereby reducing the speed of the driven high-speed shaft 31 being pulled by the low-speed shaft 13, so as to use its own deceleration system in conjunction with the device to ensure that the various components of the offshore power generation equipment are less affected by strong winds, thereby preventing locking and controlling the speed according to wave energy, handling in time, increasing stability, and improving its safety in use and maintenance effect.

[0049] The embodiment of the present invention further provides a maintenance mechanism for floating offshore power generation using wave energy, and the specific working principle includes the following steps:

[0050] When using this device, the turbine 6 is rotated according to the impact force of the ocean current, and then the mechanical energy is converted into electrical energy through the transmission 10. At the same time, the undulating motion of the waves is used to drive the first wave plate 11 and the second wave plate 12 to reciprocate. The mechanical energy is transmitted through the hydraulic wave energy converter 20 and drives the hydraulic motor 41 to rotate, so that the low-speed shaft 13 is driven to rotate, so that the first bevel gear 34 rotates accordingly, and then the meshing second bevel gear 35 is driven to rotate. After the second bevel gear 35 rotates, it drives the coaxial second main gear 23 to rotate, and further drives the meshing second sub-gear 36 to rotate, so that the short shaft 47 is driven to rotate, and then the constant speed cap 26 is driven to rotate accordingly, so that the elastic column 27 rear top block 2 is driven 9 follows the movement. When the top block 29 moves, it will move circumferentially on the inner side of the oil ring disk 14, and then reciprocately contact with the arc plate 33. When contacting a certain arc plate 33, it will drive the corresponding hydraulic rod 48 to elastically expand and contract, and contact with the spring 28. Among them, three hydraulic rods 48 will be inserted into the oil filling tank 49 when they are active, so that the lubricating oil stored in the oil filling tank 49 is regularly pushed into the transfer oil pipe 43, and further flows into the main oil vertical pipe 42, and then flows from the main oil vertical pipe 42 to the oil box 21, soaking the lower part of the first sub-gear 22. The personnel maintenance can regularly inject lubricating oil from the oil filling pipe 4 and enter the spare oil tank 15 to reserve some, and as the amount of oil in the oil ring disk 14 decreases, the lubricating oil in the spare oil tank 15 will be stored. The first main gear 17 is driven to rotate by the rotation of the low-speed shaft 13, thereby driving the meshing first sub-gear 22 to rotate. When the first sub-gear 22 rotates, it can carry the lubricating oil soaked in the oil box 21, and lubricate it with the reciprocating meshing with the first main gear 17, so that the driven high-speed shaft 31 transmits the mechanical kinetic energy to the generator 19, and transmits it through the high-speed shaft 24. The speed can be determined according to the size of the wave energy through the setting of the constant speed hood 26. When the wave energy is too large, the speed of the constant speed hood 26 is fast, so that the top block 29 has a large rotational inertia, thereby stretching the length of the elastic column 27, so that the top block 29 pushes the arc plate 33 with greater force, further allowing the arc plate 3 3 increases, and when it moves to the corresponding arc plate 33, it will drive the guide rod 50 to move at the bottom end of the oil ring disc 14. There is a sealing gasket at the position where the guide rod 50 and the oil ring disc 14 are interlaced to prevent the lubricating oil from leaking. When the guide rod 50 is pushed outward, it will drive the multi-directional connecting rod 39 to rotate along the positioning shaft rod 40, so that the guide tooth plate 38 is driven to move in the direction of the gate disc 16, and mesh with the teeth on the reduction ring 37 and drive it to rotate on the inside of the gate disc 16. As the reduction ring 37 rotates and slides, it will drive multiple pressure rods 46 to move, thereby pushing multiple brake pads 45 to frictionally reduce the speed of the brake disc 32 under the top force of the multiple pressure rods 46, thereby reducing the speed of the driven high-speed shaft 31 being pulled by the low-speed shaft 13.

[0051] The mechanical energy is transmitted through the hydraulic wave energy converter and drives the hydraulic motor to rotate, so that the low-speed shaft is driven to rotate, so that the first bevel gear follows the rotation and drives the second bevel gear to rotate, so that the coaxial second main gear rotates and drives the second sub-gear to rotate, so that the short shaft is driven to rotate and the constant speed cap follows the rotation, so that the self-adjusting control component works as a whole. Among them, three hydraulic rods will be inserted into the oil filling tank when they are active, and the lubricating oil will be regularly pushed into the transfer oil pipe, and then transported to the oil box through the main oil vertical pipe, soaking the lower part of the first sub-gear. The oil stored in the spare oil tank is replenished as the oil amount of the oil ring plate decreases. The rotation of the low-speed shaft drives the first main gear to rotate accordingly, thereby driving the meshing first sub-gear to rotate. After the first sub-gear rotates, it can carry the lubricating oil soaked in the oil box, and lubricate it as it reciprocates with the first main gear. As a result, the driven high-speed shaft transmits mechanical kinetic energy to the generator and transmits it out through the high-speed shaft. This is beneficial for use in a maintenance mechanism for floating offshore power generation that utilizes wave energy. Lubricating oil can be automatically added to internal transmission components during hydraulic power generation operations to prevent transmission friction from increasing under high-speed operation, reduce component wear, and avoid increased maintenance difficulty and time.
