The invention discloses a plant floating-bed. The plant floating-bed is composed of at least two floating-bed units connected with each other; a connecting projection is arranged on each floating-bed unit; the two adjacent floating-bed units are movably connected in a hinging manner by use of the connecting projections so as to realize mutual up-and-down flip-flop movement; at least one placing hole is formed in one floating-bed unit and a plant planting basket is placed in the placing hole; the floating-bed unit further comprises a cylindrical pin. The plant floating-bed is characterized in that a plurality of floating-bed units are movably connected in the hinging manner by use of the connecting projections and the cylindrical pin on the floating-bed units so that two adjacent floating-bed units can be mutually turned over up and down; the plant floating-bed is capable of rising and falling to swing up and down or be bent along with wind wave on the water surface of heavy wind wave, and therefore, the acting force and the moment on the plane of the plant floating-bed are reduced, the wave resistance and the structural strength of the plant floating-bed are greatly improved and the service life of the plant floating-bed is greatly increased.

The invention discloses a support device for an overwater solar photovoltaic array. The support device for the overwater solar photovoltaic array comprises a floating part and a photovoltaic support. The floating part floats on the water surface, and the photovoltaic support is fixed to the floating part; the floating part comprises a plurality of floating tubes in the same shape and of the same size, and the floating tubes are horizontally arranged in parallel at equal intervals; the photovoltaic support is provided with a plurality of supporting units, and a passage space is reserved between every two adjacent supporting units on the same floating tube; two adjacent supporting units arranged on two adjacent floating tubes correspondingly are located on the same straight line, and each supporting unit is composed of a high fixing support body and a low supporting frame which are used for fixing the two ends of a solar panel, wherein the high fixing support body is provided with a hook, a top bracing groove is formed in a matched position of the low supporting frame, the hook is buckled with one end of the solar panel, and the other end of the solar panel is braced through the top bracing groove in a matched mode, so that the solar panel is fixed; and a positioning hole perpendicular to the corresponding floating tube is formed in the lower end of each high fixing support body, and a connecting rod penetrating through the positioning holes located on the same straight line so as to fix the adjacent floating tubes.

The invention discloses a double-wing deep-water net cage suitable for single point mooring. The net cage is provided with a frame system and a net, wherein the frame system floats on the sea surface,and is provided with a mooring point for connecting a single-point mooring system, and the net is hung on the frame system; the frame system is of an axisymmetric frame structure, and the mooring point is located on the symmetry axis of the frame system and at the forefront of the frame system; and the frame system is provided with a left wing frame piece and a right wing frame piece which are arranged symmetrically along the symmetry axis, the front edge of the left wing frame piece and the front edge of the right wing frame piece are inclined straight edges inclined to the symmetry axis, and the inclined straight edges incline and extend from the inside to the outside of the frame system according to a direction from the front end to the rear end of the frame system; and angles betweenthe inclined straight edges and the symmetry axis are 30-60 degrees. The net cage has the advantages of strong incident flow stability and strong wave resistance, high rigidity of the whole frame system and good rotation stability when the direction of water flow changes.

The invention discloses a horizontal straight-through pipe double-cavity wave force power generation device. The device comprises a buoyancy tank, a horizontal straight-through pipe, oscillating watercolumn power generation modules and mooring systems. The oscillating water column power generation modules include the first power generation module and the second power generation module. The firstpower generation module comprises a first cuboid cavity, a first air turbine and a first generator; and the second power generation module comprises a second cuboid cavity, a second air turbine and asecond generator. The buoyancy tank is arranged on the upper portion of the horizontal straight-through pipe and internally provided with power storage equipment. The lower portions of the first cuboid cavity and the second cuboid cavity are immersed into water. A first water column is formed on the lower portion of the first cuboid cavity, and a first air chamber is formed on the upper portion ofthe first cuboid cavity. A second water column is formed on the lower portion of the second cuboid cavity, and a second air chamber is formed on the upper portion of the second cuboid cavity. The mooring systems comprise anchor gears, anchor chains and anchors. The horizontal straight-through pipe double-cavity wave force power generation device is high in stability and wave resistance, the reflected wave energy is reduced, the conversion efficiency is improved, the ship towing oil consumption amount is reduced, and energy saving and environment friendliness are achieved.
