Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] Reference Figure 1-9 As shown: A hybrid positioning offshore platform includes a placement platform 1, with tidal power generation devices 2 installed on both sides of one end of the placement platform 1, a force unloading device 3 installed at one end of the tidal power generation device 2, a fixing device 4 installed at the upper end of the placement platform 1, and a power transmission device 5 installed at the upper end of the placement platform 1.

[0038] The tidal power generation device 2 includes two sets of cylinders 21, a protective shell 27, and a support frame plate 24. One end of each set of cylinders 21 has a square hole 22. A round cover 23 is fixedly installed on the upper end of each set of cylinders 21. A double-sided toothed plate 25 is slidably installed on the upper end of each round cover 23. Round seats 26 are slidably installed inside each set of cylinders 21. A buffer assembly 28 is fixedly installed on the upper end of each round seat 26. A placement plate 29 is fixedly installed on the bottom end of the support frame plate 24. Two sets of support bases 210 are fixedly installed on the upper end of the placement plate 29. A generator 211 is fixedly installed on the upper end of the placement plate 29. Rotary rods 212 are rotatably installed in the middle of each set of support bases 210, near the two side edges. Rotary rods 212 are fixedly installed on the outer walls of each set of rotating rods 212. The drive gear 213, and the transmission rod 214 is rotatably mounted on one end of another set of support bases 210. The outer wall of one set of rotating rods 212 is fixedly mounted with a transmission gear 215. The transmission rod 214 is fixedly mounted with a connecting gear 216. The teeth of the two ends of the double-sided toothed plate 25 mesh with the outer walls of the two sets of rotating gears 213 respectively. The upper part of the double-sided toothed plate 25 passes through the upper ends of the protective shell 27 and the support frame plate 24 respectively. The lower end of the protective shell 27 is fixed to the upper end of the round cover 23. The generator 211, rotating gear 213, transmission gear 215 and connecting gear 216 are all located inside the protective shell 27. The other end of the transmission rod 214 is fixed to the output end of the generator 211. The lower end of the double-sided toothed plate 25 is fixed to the upper end of the buffer assembly 28.

[0039] The power transmission device 5 includes a protective box 51. Power generation and conduction components 52 are fixedly installed on the upper end of the platform 1 and near the two side edges. A transformer 53 is fixedly installed on the upper end of the protective box 51. A storage battery 54 is installed inside the protective box 51. Two sets of generators 211 are electrically connected to two sets of power generation and conduction components 52 respectively. Both sets of power generation and conduction components 52 are electrically connected to the storage battery 54. The storage battery 54 is electrically connected to the transformer 53.

[0040] In this embodiment, by providing a tidal power generation device 2, when a tide occurs, seawater rushes into the interior of the cylinder 21 through the square hole 22 and moves upward, pushing the circular seat 26 to slide upward inside the cylinder 21. The circular seat 26 pushes the double-sided toothed plate 25 upward through the buffer assembly 28, so that the double-sided toothed plate 25 moves upward between the circular cover 23, the protective shell 27, and the support frame plate 24. Under the meshing of the double-sided toothed plate 25 with the two sets of rotating gears 213, the double-sided toothed plate 25 will drive the two sets of rotating gears 213 to rotate, so that the two sets of rotating gears 213 drive the two sets of rotating rods 212 to rotate inside the two sets of support seats 210 respectively. Moreover, one set of rotating rods 212 will also drive the transmission gear 215 to rotate. The transmission gear 215 drives the connecting gear 216 to rotate. The connecting gear 216 drives the transmission rod 214 to rotate inside one set of support seats 210. At the same time, the transmission rod The other end of 214 drives the generator 211 to operate. The generator 211 is repeatedly pushed upward by the repeated impact of the tide on the circular seat 26. This operation is repeated continuously, allowing the generator 211 to rotate continuously and generate electricity. This enables tidal power generation. Combined with the use of fuel oil, it is convenient to use a hybrid power system on the positioning offshore platform. The platform can flexibly switch between fuel oil and electricity under different operating conditions, thereby reducing fuel consumption and exhaust emissions, achieving the goal of energy conservation and emission reduction, preventing the impact on air quality and human health, and preventing pollution of the ocean. At the same time, it improves energy utilization efficiency, reduces operating costs, and enhances reliability and redundancy. In case of emergency, the power system can serve as a backup energy source to ensure the normal operation of the platform's key equipment and systems.

[0041] With the cooperation of another set of rotating rods 212 and another set of rotating gears 213, the double-sided toothed plate 25 can be provided with auxiliary support, improving the stability of the double-sided toothed plate 25 when moving up and down, and preventing the double-sided toothed plate 25 from shifting laterally when moving.

[0042] The buffer assembly 28 can buffer the impact, prevent direct impact on the double-sided toothed plate 25, and protect the two sets of double-sided toothed plates 25. The protective shell 27 can protect the generator 211, the rotating gear 213, the transmission gear 215 and the connecting gear 216.

[0043] With the cooperation of two sets of tidal power generation devices 2, the storage of power resources is accelerated, which can ensure the subsequent use of power resources;

[0044] The power generation conduction assembly 52 is composed of a voltage regulator, a rectifier, and a charging circuit. Through the coordinated work of the components in the power generation conduction assembly 52, the electrical energy generated by the generator 211 can be effectively stored in the battery 54. The protective box 51 can protect the battery 54 and extend its service life.

[0045] Example 2

[0046] like Figure 1 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the unloading device 3 includes a long seat 31, two sets of fixed seats 32, and six sets of stabilizing ring seats 38. Each of the two sets of fixed seats 32 has a mating seat 33 fixedly installed at one end. A buffer 37 is fixedly installed inside the long seat 31. Push rods 35 are installed inside the two sets of mating seats 33. Two sets of triangular support plates 36 are fixedly installed on one side of the long seat 31. A sealing block 34 is fixedly installed inside the long seat 31 at both edges. The long seat 31 also has a sealing block 34 at the two sets of buffers 38. A second sealing block 39 is fixedly installed on one side of 7. The outer walls of the six sets of stabilizing ring seats 38 are fixed to the inner walls of the long seat 31. The other ends of the two sets of push rods 35 pass through one end of the two sets of first sealing blocks 34, the six sets of stabilizing ring seats 38 and the two sets of second sealing blocks 39 respectively, and are fixed to the buffer ends of the two sets of buffers 37. The inner walls of the two sets of fixed seats 32 are fixed to the outer walls of the two sets of cylinders 21 respectively. One end of the two sets of triangular brackets 36 is fixed to the inner two side walls of the placement platform 1 respectively.

[0047] In this embodiment, by providing a force-relieving device 3, when the two sets of cylinders 21 are impacted by seawater, the two sets of cylinders 21 push the two sets of mating seats 33 to move through the two sets of fixed seats 32. The two sets of mating seats 33 push the two sets of push rods 35 to move inside the long seat 31, and the two sets of push rods 35 transmit the impact force to the two sets of buffers 37. Under the action of the two sets of buffers 37, the impact force can be relieved, thereby relieving the impact force on the two sets of cylinders 21, thus preventing continuous impact from damaging the two sets of cylinders 21 and improving the service life of the two sets of cylinders 21.

[0048] With the cooperation of six sets of stabilizing ring seats 38, the two sets of push rods 35 will slide in the middle of the two sets of stabilizing ring seats 38 when they move, which can play an auxiliary role for the two sets of push rods 35 and improve the stability of the two sets of push rods 35 when they move.

[0049] The two sets of No. 1 sealing blocks 34 can seal both ends of the long seat 31 to prevent seawater from entering the interior of the long seat 31 and causing corrosion to the two sets of buffers 37, so as to ensure that the two sets of buffers 37 will not rust. The two sets of No. 2 sealing blocks 39 can further enhance the sealing effect and improve the protection of the two sets of buffers 37.

[0050] Example 3

[0051] like Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, the fixing device 4 includes two sets of fixing plates 41 and two sets of counterweights 43. L-shaped blocks 42 are inserted into one end of each set of counterweights 43 at both side edges. Placement boxes 44 are fixedly installed on the upper end of the placement platform 1 at both side edges. A lower pressure plate 45 is provided on the upper end of each set of counterweights 43. Two sets of cylinders 46 are fixedly installed inside each set of placement boxes 44. Connecting blocks 48 are fixedly installed on the extended ends of each set of cylinders 46. The upper ends of the four sets of connecting blocks 48 are fixedly mounted with… The platform is equipped with irregularly shaped pressure blocks 49. Two sets of support blocks 47 are fixedly installed on the upper ends of the two sets of placement boxes 44. The lower ends of the four sets of L-shaped blocks 42 are fixed to the upper ends of the two sets of fixing plates 41 respectively. The inner walls of the two sets of fixing plates 41 are fixed to the outer walls of the two sets of cylinders 21 respectively. The lower ends of the four sets of irregularly shaped pressure blocks 49 are fixed to the upper ends of the two sets of lower pressure plates 45 respectively. The lower ends of the two sets of counterweights 43 are all set on the upper end of the placement platform 1. The lower ends of the four sets of irregularly shaped pressure blocks 49 are in contact with the upper ends of the four sets of support blocks 47 respectively.

[0052] In this embodiment, by providing a fixing device 4, four sets of L-shaped blocks 42 are inserted into the interiors of two sets of counterweights 43. Under the weight of the two sets of counterweights 43, the four sets of L-shaped blocks 42 are pressed against the upper end of the placement platform 1, thus limiting the movement of the two sets of cylinders 21. By activating four sets of cylinders 46, the extended ends of the four sets of cylinders 46 drive the connecting blocks 48 downwards. The four sets of connecting blocks 48 drive the four sets of irregularly shaped pressing blocks 49 downwards. The four sets of irregularly shaped pressing blocks 49... The two sets of lower pressure plates 45 move to the upper end of the two sets of counterweights 43 respectively, which can fix the two sets of counterweights 43, thereby fixing the counterweights 43 and reinforcing the two sets of counterweights 43 to limit the four sets of L-shaped blocks 42, preventing the two sets of cylinders 21 from separating from the sides of the placement platform 1. At the same time, it increases the stability of the two sets of cylinders 21. Secondly, the setting of the four sets of support blocks 47 can limit the four sets of irregularly shaped pressure blocks 49, preventing the four sets of irregularly shaped pressure blocks 49 from being pressed down excessively.

[0053] The working principle of this invention is as follows: In use, firstly, the placement platform 1 is fixed at a suitable offshore drilling location. Then, four sets of L-shaped blocks 42 are inserted into the interior of two sets of counterweight blocks 43. Under the weight of the two sets of counterweight blocks 43, the four sets of L-shaped blocks 42 can be pressed against the upper end of the placement platform 1, which can limit the two sets of cylinders 21. At this time, by activating four sets of cylinders 46, the extended ends of the four sets of cylinders 46 drive the connecting blocks 48 to move downward. The four sets of connecting blocks 48 drive the four sets of irregularly shaped pressing blocks 49 to move downward. The four sets of irregularly shaped pressing blocks 49 drive the two sets of lower pressing plates 45 to move towards the upper end of the two sets of counterweight blocks 43, which can fix the two sets of counterweight blocks 43 and strengthen the limitation of the four sets of L-shaped blocks 42 by the two sets of counterweight blocks 43, preventing the two sets of cylinders 21 from separating from both sides of the placement platform 1. At the same time, it increases the stability of the two sets of cylinders 21.

[0054] Then, during tidal phenomena, seawater rushes into the interior of the cylinder 21 through the square hole 22 and moves upwards, pushing the circular seat 26 to slide upwards inside the cylinder 21. The circular seat 26 pushes the double-sided toothed plate 25 upwards through the buffer assembly 28, causing the double-sided toothed plate 25 to move upwards between the circular cover 23, the protective shell 27, and the support frame plate 24. Under the meshing of the double-sided toothed plate 25 with the two sets of rotating gears 213, the double-sided toothed plate 25 will drive the two sets of rotating gears 213 to rotate, causing the two sets of rotating gears 213 to drive the two sets of rotating rods 212 to rotate inside the two sets of support seats 210 respectively. Moreover, one set of rotating rods 212 will also drive the transmission gear 215 to rotate, and the transmission gear 215 will drive the connecting gear... When wheel 216 rotates, connecting gear 216 drives transmission rod 214 to rotate inside one set of support seats 210. At the same time, the other end of transmission rod 214 drives generator 211 to run, so that generator 211 runs. After repeated impacts of tides on round seat 26, round seat 26 can be pushed upward repeatedly, and the above operation is repeated, so that generator 211 can rotate continuously and drive generator 211 to generate electricity continuously. The generated electricity is transmitted to the inside of battery 54 through power generation conduction component 52. Battery 54 stores the input electricity. When in use, the electricity inside battery 54 is transferred through transformer 53. After conversion by transformer 53, power can be provided to different devices.

[0055] Finally, when the two sets of cylinders 21 are impacted by seawater, the two sets of cylinders 21 push the two sets of mating seats 33 to move through the two sets of fixed seats 32. The two sets of mating seats 33 push the two sets of push rods 35 to move inside the long seat 31. The two sets of push rods 35 will transmit the impact force to the two sets of buffers 37. Under the action of the two sets of buffers 37, the impact force can be dissipated, and the impact force on the two sets of cylinders 21 can be dissipated.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
