[0035] In order to make the above objectives, characteristics and advantages of the present application more apparent, comprehensible and easier to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0036] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0037] Secondly, the "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics contained in at least one implementation of the present application. In this specification, "in one embodiment" appearing in different places does not refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0038] Embodiment 1, please refer to Figures 1 to 3 As one embodiment of the present application, the embodiment provides an offshore wind power single pile capable of dynamic balance, which comprises a single pile structure 100;

[0039] The single pile structure 100 comprises:

[0040] The steel pipe piles 101 are a plurality of steel pipe piles, which are fixed into a single pile by welding;

[0041] That is, a plurality of steel pipe piles 101 are placed in a straight line along the axis thereof, and welded and assembled;

[0042] The steel pipe pile 101 is welded by using a straight seam steel pipe, and the weld is a full penetration weld, thereby improving the strength of the single pile;

[0043] A water exchange hole 102 is provided through one of the steel pipe piles 101;

[0044] An air vent hole 103 is provided through one of the steel pipe piles 101;

[0045] The number of the air vent hole 103 and the water exchange hole 102 is at least two, which is used to cope with the case that the tidal water level changes greatly, the water exchange amount and the air exchange amount are large, and the large pressure change caused by the low exchange efficiency affects the structural strength of the single pile;

[0046] Specifically, the water exchange hole 102 is located on the outer wall of one of the steel pipe piles 101 of the single pile located in the underwater part, and the air vent hole 103 is located on the outer wall of one of the steel pipe piles 101 of the single pile located in the above-water part;

[0047] In use, since the water level of seawater changes constantly with the tide, based on the arrangement of the water exchange hole 102 and the air vent hole, the water level adjustment in the water exchange hole 102 can keep the internal and external pressure of the single pile in dynamic balance with seawater, avoid damaging the single pile due to the too large pressure difference, and at the same time of the change of the tidal level, the air vent hole 103 can discharge the gas in the single pile structure 100 to the outside, avoiding the gas in the single pile structure 100 extruding the steel pipe pile 101.

[0048] Embodiment 2, please refer to Figures 3-7 As another embodiment of the present application, different from the previous embodiment, the embodiment provides an inner platform of the dynamically balanced offshore wind power single pile, which comprises an inner platform structure 200 for assisting the work of the single pile structure 100;

[0051] An air vent pipe 201a is provided through the inner platform plate 201;

[0052] Specifically, since the inner platform plate 201 divides the steel pipe pile 101 into two spaces, when the water level rises with the tide, the water exchange hole 102 adjusts the water level in the steel pipe pile 101, ensures that the internal and external pressures of the single pile structure 100 are dynamically balanced with seawater, at this time, the gas in the space composed of the inner platform plate 201 and the steel pipe pile 101 located at the lower part of the inner platform plate 201 is compressed, the role of the air pipe 201a is to guide the gas in this part to the space composed of the inner platform plate 201 and the steel pipe pile 101 located at the upper part of the inner platform plate 201, when the gas pressure in this part of the space is too large, the gas can also be discharged to the outside of the steel pipe pile 101 through the air hole 103;

[0053] The reinforcing rib 201b is arranged at the lower end surface of the inner platform plate 201.

[0054] The reinforcing rib 201b is arranged in the shape of a U-shaped beam, which is used to balance the load received by the inner platform plate 201 and improve the load-bearing capacity of the inner platform plate 201.

[0055] The hanging table 204 is arranged on the inner platform plate 201.

[0056] Specifically, the through hole corresponding to the hanging table 204 is arranged on the inner platform plate 201, which is used to mount the external current system for monitoring the inner platform plate 201 and the steel pipe pile 101 located at the lower part of the inner platform plate 201.

[0057] The hanging table 204 is arranged on the inner platform plate 201.

[0058] The hatch 203 is arranged on the inner platform plate 201.

[0059] Specifically, the manhole corresponding to the hatch 203 is arranged through the inner platform plate 201, which is used to accommodate the work personnel to move from one side of the inner platform plate 201 to the other side for work.

[0060] In use, the inner platform plate 201 serves as a bearing plate and can bear the work personnel to work inside the steel pipe pile 101, the hatch 203 facilitates the work personnel to move on both sides of the inner platform plate 201, and the hanging table 204 is arranged to mount the detection equipment, which facilitates the work personnel to detect the single pile structure 100.

[0065] The bracket 202c is arranged at the connecting position of the inner platform ring plate 202 and the inner wall of the steel pipe pile 101;

[0066] Specifically, the bracket 202c is arranged as an arc-shaped plate, and plays a role of strengthening the connecting strength of the inner platform ring plate 202 and the inner wall of the steel pipe pile 101;

[0067] The grounding stud 205 is arranged on the inner platform ring plate 202 and the inner platform plate 201, and the specific installation position is as follows:
