[0050] Embodiment 3

[0051] like Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, the fixing device 4 includes two sets of fixing plates 41 and two sets of counterweight blocks 43. One end of the two sets of counterweight blocks 43 and the edges of both sides are plugged with L-shaped blocks 42. The upper end of the placement platform 1 and the edges of both sides are fixedly installed with placement boxes 44. The upper ends of the two sets of counterweight blocks 43 are provided with lower pressure plates 45. Two sets of cylinders 46 are fixedly installed inside the two sets of placement boxes 44. The protruding ends of the two sets of cylinders 46 are fixedly installed with connecting blocks 48. The upper ends of the four sets of connecting blocks 48 are fixedly installed. It is equipped with special-shaped pressure blocks 49, two groups of support blocks 47 are fixedly installed on the upper ends of the two groups of placement boxes 44, the lower ends of the four groups of L-shaped blocks 42 are respectively fixed to the upper ends of the two groups of fixed plates 41, the inner walls of the two groups of fixed plates 41 are respectively fixed to the outer walls of the two groups of cylinders 21, the lower ends of the four groups of special-shaped pressure blocks 49 are respectively fixed to the upper ends of the two groups of lower pressure plates 45, the lower ends of the two groups of counterweight blocks 43 are both arranged on the upper end of the placement platform 1, and the lower ends of the four groups of special-shaped pressure blocks 49 are respectively in contact with the upper ends of the four groups of support blocks 47.

[0052] In this embodiment, by providing a fixing device 4, by inserting the four groups of L-shaped blocks 42 into the inside of the two groups of counterweight blocks 43 respectively, the four groups of L-shaped blocks 42 can be pressed on the upper end of the placement platform 1 under the gravity of the two groups of counterweight blocks 43 themselves, and the two groups of cylinders 21 can be limited. By starting the four groups of cylinders 46, the extended ends of the four groups of cylinders 46 drive the connecting blocks 48 to move downward, and the four groups of connecting blocks 48 drive the four groups of special-shaped pressing blocks 49 to move downward, and the four groups of special-shaped pressing blocks 49 bring The two groups of lower pressure plates 45 are moved toward the upper ends of the two groups of counterweight blocks 43 respectively, so as to fix the two groups of counterweight blocks 43, thereby reinforcing the limiting effect of the two groups of counterweight blocks 43 on the four groups of L-shaped blocks 42, preventing the two groups of cylinders 21 from separating from the two sides of the placement platform 1, and at the same time, increasing the stability of the two groups of cylinders 21. Secondly, the setting of the four groups of support blocks 47 can play a limiting effect on the four groups of special-shaped pressure blocks 49, preventing the four groups of special-shaped pressure blocks 49 from being over-pressed.

[0053] The working principle of the present invention is as follows: when in use, first, the placement platform 1 is fixed to a suitable offshore drilling location, and then the four groups of L-shaped blocks 42 are respectively inserted into the interior of the two groups of counterweight blocks 43. Through the gravity of the two groups of counterweight blocks 43 themselves, the four groups of L-shaped blocks 42 can be pressed on the upper end of the placement platform 1, which can limit the two groups of cylinders 21. At this time, by starting the four groups of cylinders 46, the extended ends of the four groups of cylinders 46 all drive the connecting blocks 48 to move downward, and the four groups of connecting blocks 48 drive the four groups of special-shaped pressing blocks 49 to move downward, and the four groups of special-shaped pressing blocks 49 drive the two groups of lower pressing plates 45 to move toward the upper ends of the two groups of counterweight blocks 43 respectively, so as to fix the two groups of counterweight blocks 43, and strengthen the limiting effect of the two groups of counterweight blocks 43 on the four groups of L-shaped blocks 42, so as to prevent the two groups of cylinders 21 from separating from the two sides of the placement platform 1, and at the same time, increase the stability of the two groups of cylinders 21.

[0054] Then, when a tide occurs, seawater rushes into the interior of the cylinder 21 through the square hole 22 and moves upward, pushing the round seat 26 to slide upward inside the cylinder 21. The round 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 round cover 23, the protective shell 27 and the support frame plate 24. Under the meshing of the double-sided toothed plate 25 and 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 respectively inside the two sets of supporting seats 210, and one set of rotating rods 212 will also drive the transmission gear 215 to rotate together, and the transmission gear 215 drives the connecting gear The wheel 216 rotates, and the connecting gear 216 drives the transmission rod 214 to rotate inside one of the groups of support seats 210. At the same time, the other end of the transmission rod 214 drives the generator 211 to operate, so that the generator 211 is in operation. After repeated impacts of the tide on the round seat 26, the round seat 26 can be repeatedly pushed upward, and the above operation is repeated, so that the generator 211 can rotate continuously and drive the generator 211 to continuously generate electricity. The generated electricity is transmitted to the inside of the battery 54 through the power generation conduction component 52, and the input electricity is stored by the battery 54. When in use, the electricity inside the battery 54 is transmitted through the transformer 53, and after conversion by the transformer 53, it can provide electricity to different devices;

[0055] Finally, when the two groups of cylinders 21 are impacted by seawater, the two groups of cylinders 21 push the two groups of matching seats 33 to move through the two groups of fixed seats 32, and the two groups of matching seats 33 push the two groups of push rods 35 to move inside the long seat 31, and the two groups of push rods 35 will transfer the impact force received into the two groups of buffers 37. Under the action of the two groups of buffers 37, the impact force received can be relieved, and the impact force received by the two groups of cylinders 21 can be relieved.
