The invention discloses a stabilizing device, a floating foundation and an offshore wind power generator. The stabilizing device comprises a U-shaped water chamber, wherein the U-shaped water chamber comprises a first hollow upright column, a second hollow upright column and a bottom buoyancy tank connected between the bottoms of the two upright columns, the first upright column and the second upright columns are communicated with the bottom buoyancy tank, and the top of the first upright column and the top of the second upright column are communicated through an air communication pipeline. The floating foundation is at least provided with a first upright column, a second upright column and a third upright column, and comprises at least one stabilizing device. The offshore wind power generator comprises the floating foundation, a mooring rope, a tower, vanes and a wind power generator set, wherein the mooring rope is connected with the outer edge of the floating foundation and is anchored to the seabed, the bottom end of the tower is arranged on the floating foundation, and the vanes and the wind power generator set are arranged on the top of the tower. By means of the stabilizing device, stabilizing of a floating fan can be simply and effectively achieved through a double-resonance principle.

The invention provides a sun-tracking photovoltaic power generation device, and relates to solar power generation equipment. The device comprises a support, a crossed turning mechanism, a main swing mechanism, a pitch swing mechanism and a rectangular tray bearing a solar power generation device array, wherein the crossed turning mechanism is fixed at the upper end of the support and can be connected with the center point of the tray in a biaxially swinging manner; the main swing mechanism winds or unwinds eastern and western steel cables through a main winch, the steel cables are connected with the middles of the eastern and western edges of the tray, so that the tray can swing eastwards and westwards, a main heavy punch and a main upper pulley are arranged at the upper end of the western steel cable or the eastern steel cable, and the main heavy punch is used for balancing the length difference of upward extension parts of the western and eastern steel cables when the tray swings eastward and westward; the pitch swing mechanism winds or unwinds southern and northern steel cables through an auxiliary winch, the southern and northern steel cables are connected with the middles of the southern and northern edges of the tray, then the tray can perform pitch swinging, an auxiliary heavy punch and an auxiliary upper pulley are arranged at the upper end of the southern or northern steel cable, and the auxiliary heavy punch is used for balancing the length difference of upward extension parts of the southern and northern steel cables when the tray performs pitch swinging. The anti-wind capacity can be improved.

The invention discloses a combined net rack and belongs to the technical field of building combined structures. The net rack is a quadrangular pyramid spatial net rack formed by combining tubes with high tension resistance with members made from other materials with high pressure resistance. Lower chord members are made from the tubes, upper chord members and web members are formed by the members made from the other materials, and all the members are connected through plate-type joints. Supports are arranged in the proper positions of the lower portions of lower chord joint plates, so that the whole structure is fixed to supporting structures. The net rack is suitable for square or rectangular structures such as roofs and canopies. Compared with net racks of traditional steel structures, the net rack has the advantages of being small in steel consumption, low in self weight, simple in structure, convenient to manufacture and mount, low in cost, good in mechanical performance and the like.

The invention discloses a four-column semi-submersible offshore floating platform, which includes two box-shaped components and four columns; the box-shaped component includes a component body and four laterally distributed arm-shaped parts, and the four arm-shaped parts are distributed around Around the component body; adjacent arm-shaped pieces are perpendicular to each other; two box-shaped components are distributed up and down; the bottom of each arm-shaped piece of the upper box-shaped component is fixed to the top of a column respectively; The top of each arm of the box member is respectively affixed to the bottom of a column. The invention has a simple structure and is convenient for large-scale batch construction; the structure has redundant stability and can reduce the steel consumption of the structure.

The invention discloses a multi-module structure for a three-dimensional box-type fabricated lightweight steel structure and a connecting mode thereof and relates to the technical field of construction. Upper guide rails, corner columns and lower guide rails form frame modules, and the frame modules are connected through corner parts, vertical bolts, horizontal bolts, longitudinal bolts and connecting plates. The corner parts are welded at the upper ends and the lower ends of the corner columns, and the connecting plates are arranged between the corner parts of upper and lower layers of frame modules. The longitudinal bolts sequentially penetrate through pad plate limiting holes located on the same layer pad plates, front and rear holes of the corner parts at the lower ends of the corner columns in the front, front and rear holes of the corner parts at the lower ends of the corner columns in the back and pad plate limiting holes formed in the pad plates and then are connected and fixed through nuts. Interior decoration work can be completed in a factory, the structure steel amount is obviously reduced, and meanwhile members are light and convenient, so that the multi-module structure is quicker to install. A lightweight steel wall can be changed according to the change of room opening requirements and building size, convenience is brought to installation of heat insulation layers and line pipelines, and the factorization degree and construction speed are high.
