4results about How to "Strong buoyancy" patented technology

The present invention relates to a buoy system, comprising: a buoy body; and an anchoring device, which is arranged below the buoy body and is used to stabilize the buoy body, and the buoy body comprises: a main cabin, at the bottom of which the anchoring device is arranged; a mast, which is arranged above the main cabin; a plurality of brackets, which surround the side of the main cabin; and a plurality of outer wall components, which are fixed on the brackets and fixed on the outer side of the main cabin, and form a closed floating chamber with the brackets and the side of the main cabin. The present invention realizes structural modularization, simplifies the production process, and is convenient for transportation and loading and unloading. It can be deployed and recovered by small and medium-sized fishing vessels and engineering ships, reducing the cost of using ships, and optimizes its internal space structure. A variety of equipment can be installed in the buoy to meet monitoring requirements.

The utility model discloses a novel carbon fiber lure lure, which relates to the field of fishing gear, and comprises a shell, a filler is arranged in the shell, a balancing weight is fixedly arranged in the filler, and a plurality of hanging rings are fixedly arranged outside the shell. By arranging the shell made of the carbon fiber material, compared with a metal bait, the bait has higher safety and higher strength than a plastic bait, the bait is prevented from being bitten by a fish during fishing, the service life is prolonged, the density of the bait is higher, the buoyancy of the bait is stronger than that of the plastic bait, the swimming stroke in water is more natural, and the bait is more attractive. Meanwhile, under the same size, a larger balance weight can be achieved, the ultra-small size and ultra-long shot can be achieved, and the throwing and fishing success rate is increased.

This utility model provides a suspended floating support device for river sediment monitoring, including a floating support mechanism, a suspension mechanism, and a power mechanism. The floating support mechanism includes a floating support ring and a fixed frame on one side. A detachable mounting frame is provided in the middle of the fixed frame, and the sediment meter sensor is mounted on the detachable mounting frame. A hanging rod is connected to one side of the fixed frame, and a hanging ring is hinged to one end of the hanging rod. The suspension mechanism includes a crossbeam and a pulley on it. A hanging rope is mounted on the pulley, and a connecting collar is provided at the lower end of the hanging rope, which is connected to the hanging ring. The power mechanism includes a roller seat, and a winding roller is installed inside the roller seat. One end of the hanging rope is connected to the winding roller, and the shaft of the winding roller is connected to the power output end of a motor. This device facilitates the suspension and deployment of the sediment monitoring sensor to fix it at a suitable depth, ensuring that it can fully contact the water body being measured and preventing the sediment monitoring sensor from being exposed above the water surface or buried by sediment when the water level changes. At the same time, it facilitates subsequent maintenance and inspection, and enables real-time monitoring of river sediment.

The utility model discloses a double-layer aquaculture net cage with a variable-angle flow-reducing blade structure. The double-layer aquaculture net cage comprises an outer-layer net cage and an inner-layer net cage placed on the inner side of the outer-layer net cage. A floating body passage is arranged in a middle gap between the outer-layer net cage and the inner-layer net cage; the core advantage of the design of the double-layer aquaculture net cage is that a unique variable-angle flow-reducing blade structure and strong wind and wave resistance are achieved, water flow can be effectively controlled by adjusting the angle of the blades, impact on cultured organisms is reduced, and meanwhile the double-layer aquaculture net cage can adapt to different aquaculture environments and requirements; the inner-layer net cage adopts the hexagonal prism design, the storm resistance of the inner-layer net cage is enhanced, the stability of the culture environment is ensured, and meanwhile, the inner-layer net cage provides good buoyancy through the circular floating body and the six columns, so that the inner-layer net cage can keep a stable state on the water surface. The propellers in the inner-layer net cage can generate lift force, so that workers can clean and replace the netting conveniently.
