[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a three-dimensional offshore wind power observation platform comprises a foundation 1, a truss 2 mounted on foundation 1, and an observation platform 3 mounted on top of truss 2. Foundation 1 comprises a cylindrical base 11 and a conical base 12, which are coaxially arranged in an integrated manner. Conical base 12 has a decreasing width from top to bottom, with its top end surface flush with the top end surface of cylindrical base 11 and its bottom intersecting with the bottom of cylindrical base 11. Cylindrical base 11 is a sealed top, open bottom structure. A one-way piston 4 and a plug 5 are mounted on the top wall of cylindrical base 11. The one-way piston 4 penetrates the top wall from bottom to top to achieve a one-way seal on foundation 1. The towing rope 6 of plug 5 extends to observation platform 3. Conical base 12 is mounted on the outside of cylindrical base 11 and is filled with ballast. Wind measuring instruments are mounted on observation platform 3, while hydrological observation instruments are mounted on truss 2. In conjunction with energy facilities such as photovoltaic panels, three-dimensional observation of the marine environment can be achieved.

[0024] As can be understood, foundation 1 combines the advantages of a gravity foundation (i.e., conical base 12) and a suction tube foundation (i.e., cylindrical base 11). The interior of cylindrical base 11 is a suction tube cavity, and the conical base 12 outside it is filled with ballast. Once the observation platform is constructed, the central suction tube cavity can provide a significant amount of pull-out and compressive bearing capacity, ensuring the vertical bearing capacity of the entire structure. The ballast-filled conical base 12 can provide a certain amount of anti-overturning bearing capacity through gravity, thereby compensating for the insufficient anti-overturning bearing capacity of the suction tube foundation. Foundation 1 of this application is particularly suitable for silt geology, making up for the difficulty of traditional pile foundations in such geology.

[0025] like Figure 2As shown, the middle of the top wall of the cylindrical base 11 is provided with a first assembly hole 13, and a plurality of second assembly holes 14 are circumferentially arranged around the first assembly hole 13. The outer part of the second assembly hole 14 is provided with a check ring 15 arranged on the upper end surface of the top wall of the cylindrical base 11. The first assembly hole 13 is used for cooperating with the plug 5 for assembly, and the second assembly hole 14 and the check ring 15 are used for assembly with the one-way piston 4. In this embodiment, the second assembly hole 14 includes three, which are equally circumferentially arranged around the first assembly hole 13; the one-way piston 4 includes three corresponding to the second assembly hole 14. The position and number of the second assembly hole 14 and the first assembly hole 13 can be adjusted according to actual needs, Figure 2 It is only one of the setting modes of the reference.

[0026] As Figure 3 and Figure 4 As shown, the one-way piston 4 includes a piston head 41, which is a conical part with a top diameter smaller than the inner diameter of the second assembly hole 14 and a bottom diameter larger than the inner diameter of the second assembly hole 14. The top of the piston head 41 is provided with a buckle 42. When the one-way piston 4 is clamped and sealed with the second assembly hole 14, the piston head 41 is blocked in the second assembly hole 14, and at the same time, the buckle 42 passes out of the second assembly hole 14 and abuts against the inner wall of the check ring 15. The piston head 41 is hung on the lower end surface of the top wall of the cylindrical base 11 through a traction member 43, and the position of the piston head 41 corresponds to the second assembly hole 14 one by one. The traction member 43 can be a traction rope or a traction chain.

[0027] The construction of the observation platform of the present application is very convenient. The conical base 12 outside the foundation 1 is a conical structure. For silt geology, under the action of self-weight, the foundation 1 can be completely self-sunk in place without the need for additional suction pumps for negative pressure sinking construction. Moreover, the one-way piston 4 is designed for the foundation 1, which can realize one-way sealing of the foundation 1, mainly through the buckle 42 to realize one-way sealing of the one-way piston 4. When the lower end surface of the piston head 41 contacts the seabed, the foundation 1 continues to sink and presses the piston head 41 and the buckle 42 into the second assembly hole 14. After the buckle 42 is pressed into the second assembly hole 14, the buckle 42 will be opened and stuck with the check ring 15, and the piston head 41 is clamped in the second assembly hole 14 and cannot move downward any more, thereby realizing the sealing of the second assembly hole 14 at this position, without the need for the complex operation of removing the suction pump and resealing by using underwater robots during the construction of traditional suction cylinder foundations.

[0028] In order to facilitate the reuse of the observation platform of the present application, the plug 5 is provided, and the traction rope 6 of the plug 5 extends to the observation platform 3. When the observation task of the observation platform is completed and needs to be removed to other places, the plug 5 is pulled up by the traction rope 6 to make the plug 5 separate from the first assembly hole 13. The pressure in the cylindrical base 11 is relieved through the first assembly hole 13, and the cylindrical base 11 is not sealed, so that the whole observation platform can be lifted by the crane and then shifted.

[0029] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
