[0015] The present invention also provides a method for using an offshore wind power construction platform, comprising the following steps: S1. After the construction vessel approaches the offshore wind power equipment, the most appropriate number of the construction platforms to be used is calculated according to the actual size of the offshore wind power equipment, and all the construction platforms of this number are connected end to end in sequence through connecting rings to form the construction platform group, and then the construction platform group is put into the sea surface, and the driving wheel on the construction platform at the head end is started to drive the entire construction platform group to move close to the offshore wind power equipment; S2. When the construction platform at the very front end is close to the offshore wind power equipment, it is connected to the offshore wind power equipment using a connecting chain. Then, the connecting sleeve on the construction platform at the very front end is close to the offshore wind power equipment, and the magnetic suction plate is magnetically attracted to the offshore wind power equipment. At the same time, the suction cup is used to adsorb on the side wall of the offshore wind power equipment. At this time, the driving wheel of the construction platform at the very front end is closed; after the suction cup at the very front end is adsorbed on the offshore wind power equipment, the sliding plate slides to connect the suction cup with the connecting sleeve. At this time, the flow-sensing impeller acts to extract the air in the suction cup, that is, the construction platform at the very front end completes the connection with the offshore wind power equipment; S3, start the construction platform at the rear end, move it around the offshore wind power equipment, and then connect the connection ring at the rear end of the construction platform at the rear end with the connection ring at the front end of the construction platform at the front end, so that the entire construction platform group surrounds the offshore wind power equipment, and repeat the steps in S2 to connect all the remaining construction platforms with the offshore wind power equipment, thereby completing the connection between the entire construction platform group and the offshore wind power equipment; S4, driving the motors on all the construction platforms to slide the secondary floating plates of all the construction platforms relative to their front sides, thereby increasing the contact area with the sea surface. At the same time, the moving frame moves to release the counterweight ball, which sinks into the sea surface, thus changing the center of gravity of the construction platform. At this time, the entire construction platform group is finally fixed and installed, and the construction workers can board the offshore wind power equipment through the construction platform; S5. After completing the maintenance inspection, when it is necessary to return or inspect the next offshore wind power equipment, open the connection sleeve to release the air, release the connection between all the suction cups and the offshore wind power equipment, release the connection between the connection chain and the offshore wind power equipment, perform the above two steps on all the construction platforms, and then release the connection between the tail end connection ring of the construction platform at the rear end and the head end connection ring of the construction platform at the head end. In this process, the connection between the magnetic suction plate and the offshore wind power equipment is automatically released, and finally the construction platform at the head end is driven to move.

[0016] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. By utilizing the connection function of the suction cup and the magnetic suction plate, the construction platform can be stably connected to the offshore wind power equipment. Through the arrangement of the flow-sensing impeller, the connecting piece and the suction chamber, the greater the wind and waves at sea, the stronger the connection effect of the suction cup. Thus, the connection effect of the suction cup is ensured, so that the construction platform can be relatively still when connected to the offshore wind power equipment, and the construction workers can easily board the offshore wind power equipment for maintenance, thereby improving the safety of the construction platform.

[0017] 2. By adding a counterweight ball that can drop suddenly, the center of gravity of the construction platform can be instantly dropped when in use, thereby improving the stability of the construction platform at sea. By unfolding the secondary floating plate, the buoyancy support of the construction platform can be increased. Therefore, the addition of the counterweight ball and the secondary floating plate are used to prevent the construction platform from being easily overturned by the ocean current and prevent the connection effect of the suction cup from being affected by the ocean current.

[0018] 3. The fold-slowing plate is used to prevent the wire rope from being damaged at the opening on the installation frame Y. At the same time, the sliding fold-slowing plate can also buffer the movement of the counterweight ball. The rotating plate is used to receive the counterweight ball to prevent the counterweight ball from hitting the installation frame Y and damaging the installation frame Y. That is, the addition of the fold-slowing plate and the rotating plate can optimize the use of the counterweight ball.

[0019] 4. The buffer frame can buffer the impact force when the two construction platforms are close to each other, thereby improving the safety of the construction platforms. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Embodiment 1: An offshore wind power construction platform, see Figure 1-Figure 2, including: a support base 1, which is used by construction workers or related personnel or for loading maintenance equipment; a main floating plate 2 installed at the bottom of the support base 1 to increase the buoyancy of the support base 1 so that the support base 1 has sufficient buoyancy to float on the sea surface; connecting rings 11 installed on the left and right sides, through which the construction platform can be connected end to end, and multiple construction platforms can be combined and connected for use.

[0041] See also Fig.10 and Fig.17 , and also includes: a connecting chain 7 respectively installed on the left and right sides of the rear side of the support seat 1, which can be used to connect with the offshore wind power equipment; a driving wheel 13 installed on the left side of the main floating plate 2, and the driving wheel 13 can be used to drive the construction platform to move on the sea; using the construction platform for movement, compared with a large construction ship, it can be more flexible to travel between offshore wind power equipment, providing convenience for the maintenance work of the construction workers.

[0042] See also Figure 3-Figure 4 , further comprising: a mounting plate 31 mounted at the bottom of the main floating plate 2; a sliding frame 32 slidably mounted on the mounting plate 31, the sliding frame 32 slides back and forth; a compression elastic member X33 mounted on the sliding frame 32, in this embodiment, the compression elastic member X33 is a compression spring, the compression elastic member X33 is connected between the sliding frame 32 and the mounting plate 31, and the compression elastic member X33 automatically returns the sliding frame 32 to its original position after the position of the sliding frame 32 changes; an air pumping chamber 3 mounted on the mounting plate 31; a sliding member X33 mounted on the air pumping chamber 3, the piston plate 34 is composed of a piston part and a sleeve part, the piston part of the piston plate 34 is in the air pumping chamber 3, when the piston plate 34 slides, it will push and draw the air in the air pumping chamber 3 and the parts connected with the air pumping chamber 3; the limiting rod 36 installed on the front side of the rear part of the sliding frame 32, the sleeve part of the piston plate 34 is sleeved outside the limiting rod 36, which guides the movement of the piston plate 34; the one-way valve 35 installed in the air pumping chamber 3, when the piston plate 34 moves, the air in the air pumping chamber 3 will be pushed out from the one-way valve 35.

[0043] See also Figure 4-Figure 6, further comprising: a connecting rod 41 installed at the rear side of the rear of the sliding frame 32; a connecting sleeve 4 installed at the rear end of the connecting rod 41 is rotatable, and the connecting sleeve 4 can be sealed and unsealed for venting; a torsion elastic member 42 installed between the connecting sleeve 4 and the connecting rod 41. In this embodiment, the torsion elastic member 42 is a torsion spring. After the position of the connecting sleeve 4 changes, the torsion elastic member 42 automatically returns the connecting sleeve 4 to its original position, so that the connecting sleeve 4 itself can perform an adaptive change in angle folding, and the sliding sliding frame 32 and the compression elastic member X33 cooperate to enable the connecting sleeve 4 to perform an adaptive change in the front and rear positions; two magnetic suction plates 4 installed on the left and right sides of the rear side of the connecting sleeve 4 3. The magnetic plate 43 can be magnetically connected to the side wall of the offshore wind power equipment. First, position the connecting plate 4 on the side wall of the offshore wind power equipment; install the mounting ring 51 on the rear side of the connecting plate 4. There are ten mounting rings 51, which are evenly distributed on the connecting plate 4. All mounting rings 51 are between the two magnetic plates 43; correspondingly install the suction cup 5 on each mounting ring 51; slide the sliding plate 52 on each mounting ring 51. The sliding plate 52 is composed of a circular plate portion and a rod portion. The circular plate portion of the sliding plate 52 is inside the connecting plate 4, and the rod portion of the sliding plate 52 is outside the mounting ring 51; the compression elastic member Y53 is sleeved on the rod portion of the sliding plate 52. In this embodiment, the compression elastic member Y53 is a compression spring, and the compression spring Y53 is connected between the rod of the sliding plate 52 and the mounting ring 51, and the compression spring Y53 makes the sliding plate 52 and the mounting ring 51 close to each other; when the suction cup 5 is adsorbed on the offshore wind power equipment, the side wall of the suction cup 5 is displaced, and the suction cup 5 will push the sliding plate 52 forward, and the sliding plate 52 leaves the mounting ring 51, so that the suction cup 5 is connected with the connecting sleeve plate 4; two one-way ventilation pipes 44 are installed and connected between the exhaust chamber 3 and the connecting sleeve plate 4, and the one-way ventilation pipe 44 is a one-way passage. When the piston plate 34 slides forward, the air in the suction cup 5 will be extracted through the one-way ventilation pipe 44 and the connecting sleeve plate 4, and when the piston plate 34 slides backward, the exhaust chamber 3 is pushed out from the one-way valve 35, but not from the one-way one-way vent pipe 44 to the suction cup 5. It should be noted here that only the suction cup 5 adsorbed to the side wall of the offshore wind power equipment can push the sliding plate 52 to connect with the connecting sleeve 4, while the suction cup 5 not adsorbed to it will not be connected with the connecting sleeve, and will not be affected by the suction chamber 3. In this way, it can be prevented that the suction cup 5 is not completely adsorbed to the offshore wind power equipment due to the influence of the connection part with the offshore wind power equipment, resulting in the suction cup 5 being deflated and affecting normal use. In addition, the elastic force of the compression spring Y53 is much greater than the suction pressure generated when the piston plate 34 slides. When the piston plate 34 slides to suck air, the sliding plate 52 cannot be moved.

[0044] See also Figure 7-Figure 9, further comprising: a mounting frame X61 mounted at the bottom of the main floating plate 2, the mounting frame X61 being at the bottom of the mounting plate 31; a flow-sensing impeller 6 mounted at the bottom of the mounting frame X61 being rotated, the flow-sensing impeller 6 being rotated by the action of the ocean current; a turntable 62 mounted in the mounting frame X61 being rotated, the turntable 62 being connected to the flow-sensing impeller 6; a guide rod 63 mounted in the mounting frame X61; a slideway 64 slidably connected to the guide rod 63, the direction of the slideway 64 being perpendicular to the guide rod 63, the slideway 64 sliding back and forth on the guide rod 63; a convex rod 65 mounted on the turntable 62, the convex rod 65 sliding in the slideway 64; a connecting frame 66 mounted at the rear end of the slideway 64, the connecting frame 66 being also fixedly connected to the sleeve portion of the piston plate 34; the rotation of the flow-sensing impeller 6 drives the turntable 62 to rotate, so that the rotation The protruding rod 65 on the disk 62 is displaced, and because the protruding rod 65 slides in the sliding groove 64, the left and right displacement of the protruding rod 65 is offset by the sliding groove 64, and the forward and backward displacement of the protruding rod 65 will cause the sliding groove 64 to move forward and backward, that is, the piston plate 34 will be driven to move forward and backward through the connecting frame 66, and the air in the air extraction chamber 3 will be pumped out, that is, the sea water will fluctuate, which will cause the flow-sensing impeller 6 to rotate. The greater the amplitude of the sea water fluctuation, the faster the flow-sensing impeller 6 rotates, the faster the speed of pumping the air in the air extraction chamber 3, and the faster the air in the suction cup 5 is pumped away, so that the suction cup 5 can be more firmly adsorbed to the side wall of the offshore wind power equipment, until the air in all the suction cups 5 is sucked to the limit, the piston plate 34 will no longer be able to pump air, the piston plate 34 will no longer move, and the flow-sensing impeller 6 will also stop rotating.
