Offshore wind power negative-pressure barrel base capable of removing soil plugs

Abstract

The invention discloses an offshore wind power negative-pressure barrel base capable of removing soil plugs. The offshore wind power negative-pressure barrel base capable of removing soil plugs comprises a barrel body. A vertical barrel is arranged on the upper end face of the barrel body. A bearing table is horizontally arranged on the upper portion of the vertical barrel. The top of the barrel body is further provided with drainage holes communicating with the interior of the barrel body. Four rotary sprayers are installed on the inner top of the barrel body symmetrically through bearings. The inner ring of each bearing and a barrel body top cover are connected into a whole. Each bearing is hollow, so that a channel for the corresponding rotary sprayer is formed, and the channels are connected with the outside. The upper half portion of each rotary sprayer is a hollow short tube, and the upper end of each hollow short tube and the outer ring of the corresponding bearing are fixedly connected into a whole. The lower half part of each rotary sprayer is a semicircular disc with the hollow inside, and the planar fracture surface position of each semicircular disc is in sealed connection with the lower end face of the corresponding hollow short tube. The cavity of each hollow short tube communicates with the cavity of the corresponding semicircular disc. Water guiding tubes are arranged at the arc edge of each semicircular disc, and the included angles between the water guiding tubes and the fracture surface of the corresponding semicircular disc are 0 degree, 30 degrees, 45 degrees, 60 degrees and 90 degrees correspondingly. The water guiding pipes communicate with the cavities of the semicircular discs. The negative-pressure barrel base is simple in structure, convenient to use and capable of removing soil plugs.

Description

Technical field [0001] The invention relates to a civil engineering technology, in particular to a negative pressure cylinder base for offshore wind power that can eliminate soil clogging. Background technique [0002] As a kind of clean renewable energy, wind energy has the characteristics of inexhaustible and inexhaustible, so it has attracted more and more attention from all countries in the world. my country has a long coastline and rich wind energy resources in offshore areas. Therefore, offshore wind farms have broad prospects for development in my country. With the continuous development of wind power, the total number of wind turbines on land has become saturated. Its many advantages will surely become the focus of future development. [0003] The development prospects of offshore wind power are broad, and the economics, safety and stability of offshore wind turbine infrastructure have become the focus of current research. According to the existing research results and the...

Problems solved by technology

The foundation includes steel pipe single piles constructed on the seabed by sinking piles, and a composite structure is set on the single piles. The composite structure includes pile casings, ring beams, truss structures and negative pressure cylinder structures. The foundation can make full use of the surface soil near the seabed improve the vertical and horizontal load-bearing performance of the wind turbine foundation, and increase the bearing capacity of the foundation, but the foundation cannot eliminate the phenomenon of soil plugging
