The present invention relates to a thoracic aortic covered stent (100), comprising a bare stent segment (110) and a covered stent segment (120). The bare stent segment (110) comprises a bare wave-shaped ring (111); the covered stent segment (120) has a lesser curvature side region (100c), a greater curvature side region (100a), and two opposite intermediate regions (100b) located between the lesser curvature side region (100c) and the greater curvature side region (100a) respectively; and the covered stent segment (120) comprises a first proximal wave-shaped ring (121). The stent (100) further comprises a first connecting member (131), a first side connecting member (132) and a second side connecting member (133) all connected to the bare wave-shaped ring (111) and the first proximal wave-shaped ring (121), wherein the first connecting member (131) is arranged in the lesser curvature side region (100c), and the first side connecting member (132) and the second side connecting member (133) are arranged in the two intermediate regions (100b) respectively. The stent (100) when located near the lesser curvature side (22) with a relatively small radius of curvature has a connecting assembly rigidly connecting the bare stent segment (110) and the covered stent segment (120), and through the constraints thereof, the bare stent segment (110) can be effectively prevented from overturning towards the vessel wall during the release process, so that the proximal end of the covered stent segment (120) is securely apposed to the wall, thereby avoiding the “turnover” effect.

The invention discloses a purification method for eliminating fine particle pollutants in near-coastal sea areas, which is set in the field of environmental treatment. The method comprises the following steps: throwing purification components in the waters of near-coast sea areas, and connecting adjacent purification components with connecting anchor ropes And on the land near the shore, there are fixed piles connected with the anchor ropes. The purification component includes a buoyant purification base. The purification base has a disc-shaped bottom plate. The first filter screen is set around, the bottom plate of the inner middle part of the cylindrical sleeve-shaped body is provided with a disc-shaped protrusion, the upper part of the disc-shaped protrusion is provided with a rotating base, and the disc-shaped protrusion and the middle part of the assembled disc Coaxial first flow holes are all provided. The invention realizes the automatic purification of nearshore water bodies, rapidly separates microplastic particles of different particle sizes in the water body and intercepts the microplastic particles for centralized treatment, and effectively improves the light transmittance of nearshore water layers.

The invention discloses an intercooler of a double-wave inner-fin structure. The interior of a radiating tube is provided with a double-wave inner fin. The double-wave inner fin comprises an upper inner fin, a lower inner fin and a flat fin in the middle. The flat fin is connected with the upper inner fin and peaks of the lower inner fin. Outermost waves at two end portions of the upper inner fin and the lower inner fin are matched with four corners R of the radiating tube in order to form a double-layer composite structure. Two ends of the flat piece are provided with signal sides or overturn sides on two sides. The overturn sides and short sides of the radiating tube are matched in order to form a double-layer composite structure. Without increasing cost, structural strength is improved.

The invention discloses a floating breakwater. The floating breakwater comprises a plurality of floating boxes which are connected to one another by connecting devices, wherein each floating box comprises an upper floating body and a lower floating body which are in contact from top to bottom and are fixedly arranged; the upper floating body is of a tortuous slope-shaped groove type steel structure, and a plurality of block-shaped energy dissipating devices are arranged on the inward bending surface of the groove of the upper floating body; the lower floating body is a rectangular body made of a high-strength polypropylene material, and a plurality of wave dissipating holes which are perforated and staggered are formed in the lower floating body; and the floating banks are provided with mooring guide rope holes which are used for connecting guide ropes so as to moor the floating boxes in water. The floating breakwater has the beneficial effects that the floating breakwater has a good wave dissipating effect under terrible ocean environments and long-period waves and is simple in structure; and the width of the breakwater is unlimited due to adoption of modular assembly, thereby facilitating offshore construction and later maintenance.
