TECHNICAL FIELD

[0001] The present application relates to the technical field of wind turbine installation, in particular to a mounting structure of wind turbine accessory. BACKGROUND

[0002] With the transformation of global energy structure, offshore wind energy development as a clean energy gradually enters a new stage. Compared with onshore wind power, offshore wind power has many advantages such as less land occupation, less environmental impact and stable and efficient, so offshore wind power has gradually become an important support for the transformation of global energy structure. The wind power cylinder is the most important accessory in the wind turbine accessory. After the wind power cylinder is transported to the site, in the sinking process, under the action of deep water and complex sea conditions, the stability, safety and levelness of the sinking of the wind power cylinder will be difficult to meet the requirements.

[0003] Referring to the prior art CN216041270U, a kind of offshore wind power cylinder type foundation deep water sinking installation device, including mooring anchor cable, float box, tuned mass damper;Mooring anchor cable is connected between simple foundation and seabed;Float box is set on wind power cylinder;Tuned mass damper is located below float box, and is connected between cylinder type foundation and float box.

[0004] When the bottom of the wind power cylinder contacts the seabed mud surface, the float box and the tuned mass damper outside the periphery of the cylinder wall are unbuckled, the anchor chain fixed on the cylinder type foundation is unfastened, the cylinder is pumped and air is pumped to realize sinking under negative pressure until the specified elevation. However, the above-mentioned patent does not disclose how to unbuckle the float box and the tuned mass damper, and at present, manual diving to the seabed is still needed to unbuckle, and the manual diving has safety hazards, and during the process of the float box rising from the seabed to the sea surface after manual unbuckling, the float box is carried away by the sea waves, so it is not convenient to collect the float box. SUMMARY

[0005] The present application aims to provide a mounting structure of wind turbine accessory to replace manual diving salvage and realize automatic unbuckling and collection of the float box.

[0006] In order to solve the above problems, the present application provides the following technical scheme: a mounting structure of wind turbine accessory, comprising a wind power cylinder, a mooring anchor cable and a float box, the mooring anchor cable being connected between the wind power cylinder and the seabed;The wind power cylinder is provided with a vertical through slot and a mounting slot, the top of the mounting slot extends to the top of the wind power cylinder, and a mounting block is arranged in the mounting slot;A connecting slot is arranged between the through slot and the mounting slot, the connecting slot is slidably connected with a fixing block for pressing the mounting block against the inner wall of the mounting slot, a first spring is arranged between the fixing block and the connecting slot;The through slot is vertically slidably connected with an extrusion rod, the bottom of the extrusion rod extends out of the through slot, the extrusion rod is fixedly sleeved with a limiting block and a wedge, the wedge and the fixing block abut, a second spring is fixedly arranged between the through slot and the limiting block, the mounting block is further fixedly sleeved with a rope, and the float box and the mounting block are detachably connected.

[0007] The working principle and beneficial effects of the present application: the buoyancy of the floating box is controlled in the present scheme, so that the weight of the wind power cylinder is slightly greater than the buoyancy of the floating box, so that the wind power cylinder slowly descends in the sea. Since the second spring is fixedly arranged between the limiting block and the through groove, the second spring pulls and extrudes the extrusion rod upward, so that it cannot fall out of the through groove. At this time, the mounting block is located in the mounting groove, the wedge block is pressed against the fixed block, and the fixed block is pressed against the mounting block. Therefore, during the descent of the wind power cylinder, the floating box is carried downward by the mounting block.

[0008] When the wind power cylinder approaches the seabed, the bottom of the extrusion rod protrudes out of the through groove, and the bottom of the extrusion rod first contacts the seabed. The seabed pushes the extrusion rod upward in the direction toward the sea surface. The extrusion rod slides in the through groove, and the extrusion rod drives the wedge block and the limiting block to move. The limiting block extrudes the second spring upward, and the wedge block is separated from the fixed block. The compressed first spring returns to move the fixed block toward the through groove, so that the fixed block is separated from the mounting block. Therefore, the mounting block is not pressed by the fixed block and is in an active state. By pulling the rope, the mounting block is pulled out of the mounting groove (and the buoyancy of the floating box also pushes the mounting block upward). Therefore, the rope pulls the mounting block and the floating box out of the sea surface, thereby achieving automatic unbinding and collection.

[0009] Further, the floating box is symmetrically arranged along the axis of the wind power cylinder. This arrangement makes the wind power cylinder descend more stably.

[0010] Further, a tuned mass damper is further included, and the tuned mass damper is detachably connected with the floating box. The tuned mass damper includes a mass block, a third spring, and a damping block. The mass block is fixedly arranged at the bottom of the floating box. The damping block is fixedly connected with the mounting plate. The third spring is arranged between the mass block and the damping block.

[0011] Further, the bottom of the extrusion rod is fixedly sleeved with an ejection disc, and the bottom of the wind power cylinder is provided with a circular groove for accommodating the ejection disc. This arrangement can increase the contact area with the seabed plane, thereby facilitating the upward lifting of the extrusion rod.

[0012] Further, the floating box and the mounting plate are bolted.

[0013] Further, the fixed block is provided with a wedge surface on the side facing the wedge block. The wedge surface and the wedge block are used in cooperation. The contact area between the wedge surface and the wedge block is large, so that the fixed block is quickly pushed to move. BRIEF DESCRIPTION OF DRAWINGS
