[0028] like Figures 1 to 4 As shown, the utility model provides a buoy-type offshore construction platform, comprising:

[0029] A rectangular parallelepiped steel pipe frame 1;

[0030] A plurality of buoys 2 are horizontally arranged in the steel pipe frame 1 in multiple layers and multiple rows in each layer. The steel pipe frame 1 is also provided with crisscrossing limit steel pipes for limiting the movement of the buoys 2;

[0031] A decking plate 3, which is arranged on the top of the steel pipe frame 1;

[0032] A guardrail 4 is arranged along three sides of the top edge of the steel pipe frame 1;

[0033] An anchor 5 connected to a rope fixed to the deck 3 or the steel pipe frame 1;

[0034] The bottom edge of the steel pipe frame 1 is tied with a rubber wheel 6 , and the edge of the rubber wheel 6 protrudes beyond the horizontal projection range of the steel pipe frame 1 .

[0035] Specifically, the buoy 2 can be an empty oil drum, and the steel pipe frame 1 can be assembled from long steel pipes and fasteners used for scaffolding.

[0036] The floor planks 3 can be made of wooden boards and laid on the top of the steel pipe frame 1;

[0037] The four corners of the steel pipe frame 1 can be constructed by first vertical steel pipes with a height higher than the top of the steel pipe frame 1, and horizontal steel bars can be welded between the first vertical steel pipes to form a guardrail 4;

[0038] The three side walls of the steel pipe frame 1 on which the guardrail 4 is arranged can also be provided with a second vertical steel pipe having a height higher than the top of the steel pipe frame 1 and lower than the first vertical steel pipe, so that the second vertical steel pipe can support the middle part of the guardrail 4;

[0039] The limiting steel pipes are connected to the steel pipe frame 1 through fasteners. The longitudinal limiting steel pipes are used to limit the buoys 2 into columns, and the longitudinal limiting steel pipes are used to limit the buoys 2 into rows.

[0040] The rope connected to the anchor 5 can be tied to the steel pipe frame 1 or the winch 14 as described in the following embodiment is set on the deck 3.

[0041] The rubber wheels 6 can be arranged at the four corners of the bottom of the steel pipe frame 1 . Of course, in order to more comprehensively protect the buoy 2 , the rubber wheels 6 can be tied along the four edges of the bottom of the steel pipe frame 1 .

[0042] The working process of the above embodiment is as follows: the buoy 2 type offshore construction platform is connected to the tugboat by using a tow cable, and then the buoy 2 type offshore construction platform is dragged to the shore by the tugboat, and the buoy 2 type offshore construction platform is anchored by the anchor 5, and the drilling equipment is lifted from the shore to the buoy 2 type offshore construction platform by the crane on the shore, and the anchor 5 is lifted from the water, and then the buoy 2 type offshore construction platform is dragged to the construction site by the tugboat, and then the buoy 2 type offshore construction platform is anchored by the anchor 5, and then the drilling equipment can be used for operation.

[0043] Since the working environment of the pontoon 2 type offshore construction platform is generally in a shallow water area near the shore with many underwater reefs, tying a rubber wheel 6 at the bottom of the steel pipe frame 1 can prevent the pontoon 2 from hitting the underwater reefs near the shore, reduce the situation where the pontoon 2 is damaged and flooded due to hitting the reefs, and is conducive to the long-term use of the pontoon 2 type offshore construction platform.

[0044] In another embodiment, a fixing ring 7 is disposed on the outer shell of the buoy 2, and a clamp 8 for connecting with the limiting steel pipe is disposed on the outer wall of the fixing ring 7.

[0045] Specifically, the fixing ring 7 can be made of a thin steel plate strip bent into a circular shape and welded, and then the fixing ring 7 is put on the buoy 2. The clamp 8 can be welded to the outside of the fixing ring 7 in advance. When the buoy 2 is placed in the steel pipe frame 1, the clamp 8 is connected to the long steel pipe constituting the steel pipe frame 1 or the limiting steel pipe that limits the movement of the buoy 2 with bolts.

[0046] In the above embodiment, by arranging the fixing ring 7 outside the buoy 2 and arranging the clamp 8 outside the fixing ring 7, the buoy 2 is more easily connected to the steel pipe frame 1 and the limiting steel pipe.

[0047] In another embodiment, the deck board 3 is hinged with a strap 9 near the edge of the top of the steel pipe rack 1 where the guardrail 4 is not provided, and a winch 10 is also provided on the deck board 3, and the steel rope of the winch 10 is connected to the strap 9, so that the deck board 3 can be flipped over and overlapped on the shore or obliquely stood on the edge of the top of the steel pipe rack 1 where the guardrail 4 is not provided.

[0048] Specifically, a pair of ear seats are provided at the edge of the deck board 3 near the top of the steel pipe frame 1 where the guardrail 4 is not provided, and ear shafts are provided on a pair of opposite end faces of the strap board 9, and the pair of ear shafts are rotatably connected to the pair of ear seats respectively.

[0049] The working process of the above embodiment is as follows: when the buoy 2 type offshore construction platform is close to the shore, the winch 10 is started to lengthen the steel rope, and the sheathing 9 is automatically flipped over by the deadweight of the sheathing 9. When the front end of the sheathing 9 abuts against the shore, a temporary pier can be formed, which is convenient for the drilling equipment to drive onto the deck 3. When the drilling equipment is completely located on the deck 3, the winch 10 can be started to wind the steel rope, so that the steel rope pulls the sheathing 9 to flip to an oblique state, so that the sheathing 9 can temporarily form a guardrail to block the edge of the top of the steel pipe rack 1 where the guardrail 4 is not provided.

[0050] In another embodiment, a propeller 11 is disposed at the bottom of the steel pipe frame 1 , and a driving motor 12 for driving the propeller 11 is disposed on the deck 3 .

[0051] In the above embodiment, by providing a driving motor 12 and a propeller 11, a tugboat can be replaced, so that the buoy 2 type offshore construction platform can move by its own power, making construction more convenient.

[0052] In another embodiment, the four corners of the top of the steel pipe frame 1 are provided with lifting ears 13. When the buoy 2 type offshore construction platform is assembled, the lifting ears 13 can be hung by a crane to lift the buoy 2 type offshore construction platform, so as to facilitate the lifting and transfer of the buoy 2 type offshore construction platform.

[0053] In another embodiment, a winch 14 is provided at the edge of the deck board 3 , the rope is provided in the winch 14 , and a hand crank is provided on the side wall of the winch 14 .

[0054] Specifically, a long steel plate can be welded along the edge of the top of the steel pipe rack 1, and the long steel plate can provide a welding basis for the ear seat, and similarly, it can also provide a welding basis for the winch 14. The floor planks 3 in other areas of the top of the steel pipe rack 1 can be made of wooden boards.

[0055] In the above embodiment, the winch 14 and the hand crank can be provided to conveniently lengthen or retract the rope, thereby making it easy to manipulate the anchor 5.

[0056] In another embodiment, the propeller 11 is disposed below a side of the steel pipe frame 1 where no guardrail 4 is provided, and a V-shaped water dividing plate 15 is provided on the side wall of the steel pipe frame 1 opposite to the side where no guardrail 4 is provided.

[0057] In the above embodiment, by providing the water dividing plate 15, the water flow can be separated when the buoy 2 type offshore construction platform moves forward, thereby reducing the water resistance.

[0058] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
